Summary
Sickle cell anemia (SCA) can cause marrow hyperplasia in children. This case highlights unusual maxillary sinus involvement in a young boy with SCA, offering key imaging insights for diagnosis.
Area of Science:
- Hematology
- Pediatric Radiology
- Genetics
Background:
- Sickle cell anemia (SCA) is a genetic blood disorder.
- Marrow hyperplasia is a known complication of SCA, typically affecting the skull in children over five.
- Facial bone involvement, excluding the mandible and orbits, is uncommon in SCA.
Observation:
- A 28-month-old African American boy with SCA presented with unusual findings.
- He exhibited extensive marrow hyperplasia of the maxillary sinuses.
- Severe calvarial and mandibular changes were also noted.
Findings:
- Computed Tomography (CT) revealed imaging characteristics consistent with marrow hyperplasia at other sites.
- Magnetic Resonance (MR) imaging showed low signal intensity on both T1 and T2 sequences.
- These imaging features are indicative of marrow hyperplasia in the maxillary sinuses.
Implications:
- This case expands the understanding of marrow hyperplasia distribution in pediatric SCA.
- Recognizing these imaging patterns can aid in the early and accurate diagnosis of SCA complications.
- Further research into the specific mechanisms and prevalence of maxillary sinus involvement in SCA is warranted.
